Abstract: In certain aspects, a method is provided for measuring power using a resistive element coupled between a power amplifier and an antenna. The method includes squaring a voltage from a first terminal of the resistive element to obtain a first signal, squaring a voltage from a second terminal of the resistive element to obtain a second signal, and generating a measurement signal based on a difference between the first signal and the second signal. In some implementations, the resistive element is implemented with a power switch.

Abstract: Devices and techniques are described to extract specific frequency band signals from a wide-band radio-frequency signal. A network entity may include an antenna for receiving the wide-band radio-frequency signal and may include a receiver circuit for processing the wide-band radio-frequency signal. The receiver circuit may include a transconductance amplifier and a plurality of single-band circuits. The transconductance amplifier may be configured to generate an amplified wide-band radio-frequency signal and send it to one or more of the single-band circuits. Each single-band circuit may be configured to extract a different frequency band signal from the amplified wide-band radio-frequency signal.

Abstract: A phase discontinuity mitigation implementation within a phased lock loop (PLL) improves throughput of a radio access technology. The throughput is improved by maintaining a phase of the PLL while powering off some devices of the PLL, such as a local oscillator (LO) frequency divider. In one instance, when the PLL is powered down, one or more portions of a delta sigma modulator for the PLL are clocked with a reference clock for the PLL. This implementation maintains phase continuity when the first phase lock loop turns back on.

Abstract: An RF driver circuit may include a wideband output impedance matching and gain circuit, a wideband input impedance matching and gain circuit, and a summer configured to sum the outputs of the wideband output impedance matching and gain circuit and wideband input impedance matching and gain circuit. The wideband output impedance matching and gain circuit and wideband input impedance matching and gain circuit may collectively provide the gain of the RF driver circuit. The wideband output impedance matching circuit may have a source follower configuration. The wideband input impedance matching circuit may have a common gate configuration. Controllable bias voltages may be used to maintain a constant gain and interface impedances in multiple modes of operation.
